Cut Model of Automatic Transmission System AZA1249
The AZA1249 Cut Model of Automatic Transmission System by AZALAB is a precision-engineered educational trainer designed to demonstrate the construction, operation, and working principles of a hydraulic automatic transmission system used in modern passenger vehicles. Developed using a full-size original car automatic transmission, this cutaway model provides an authentic, hands-on learning experience for automotive students and technicians.
The transmission assembly is carefully sectioned and color-coded to expose all major internal components, allowing clear visualization of power flow, gear shifting logic, and hydraulic control mechanisms. Mounted on a sturdy tubular steel frame with wheels, the AZA1249 is easy to move within classrooms, laboratories, and workshops, making it ideal for group demonstrations and instructor-led training.
Description
Educational Design & Construction
The AZA1249 is manufactured from an actual hydraulic automatic transmission, ensuring real-world accuracy. All internal parts are precision cut, polished, electroplated, and color painted to highlight the interaction between mechanical and hydraulic systems. Chromium plating and galvanization protect the components from corrosion and wear, ensuring long service life even with repeated use.
The model is manually operated using a hand crank connected to the torque converter, allowing instructors to demonstrate how rotational input is transferred through the torque converter, planetary gear sets, and clutch packs. This manual operation enables students to visually follow gear engagement and understand automatic gear shifting sequences without electrical complexity.
